Hey there guys.
Im trying to launch the OS at my brand new STM32F100 discovery (
I'm handling some difficulties from beggining, can anyone lead me through this?
Im trying to compile the code, but it throws error , and dont show from what line can it possibly be. I also tryied the code from examples with two tasks, but still all i can get is the error :
.\Objects\Projektorium no 1.axf: Error: L6218E: Undefined symbol os_error (referred from rt_system.o).

//---------Basic Libraries---------------
#include <stdio.h>
//---------Custom Libraries--------------
#include "gpio_config.h"
#include "led_control.h"
#include "stm32f10x.h"
#include "RTL.h"
__task void startup     (void);
__task void heart_beat (void);
__task void startup (void) {
    STARTUP = os_tsk_self();
    for(;;) {
        os_tsk_create(heart_beat, 1);
__task void heart_beat(void) {
    HB = os_tsk_self();
    for(;;) {
int main(void)
Can someone guide me through please. I wasnt able to find anything near to this case.
Thanks in advance
